I place some adsense onto a site of mine (manufacturing engineering). Now I wonder, if it has been done properly. Are distances to text and graphics, OK?
From an adsense guidelines POV, the placement is fine depending on the image that will be placed on top. From a layout POV, you should, however, put some padding between the image and the adsense.
What is the advantage of square adds (I like the rounded edges)? What blending of Colours should be used and why?
Well I guess its against TOS now.. if you don't want to put padding, just place a line (separator) between them.
